Inverter

Abstract

An inverter includes: a step-up transformer; an upper cover for covering the step-up transformer; a terminal attached to the upper cover and electrically connected to the step-up transformer; a terminal case attached to the upper cover to cover the terminal and attachable with a connector to be plugged into and unplugged from the terminal; a first positioning unit provided to the upper cover and the terminal to position the upper cover and the terminal relative to each other; and a second positioning unit provided to the upper cover and the terminal case to position the upper cover and the terminal case relative to each other.

1 . An inverter comprising:
 an electronic component;   an inverter cover for covering the electronic component;   a terminal attached to the inverter cover and electrically connected to the electronic component;   a terminal case attached to the inverter cover to cover the terminal, the terminal case being attachable with a connector to be plugged into and unplugged from the terminal;   a first positioning unit provided to the inverter cover and the terminal to position the inverter cover and the terminal relative to each other; and   a second positioning unit provided to the inverter cover and the terminal case to position the inverter cover and the terminal case relative to each other.   
     
     
         2 . The inverter according to  claim 1 , wherein:
 the terminal case is provided with a connector-insertion opening through which the connector is inserted, and   the connector-insertion opening has an inner circumferential surface defining a seal surface to be brought into close contact with a seal member provided to an outer circumferential surface of the connector.   
     
     
         3 . The inverter according to  claim 1 , wherein the terminal comprises a terminal bracket comprising:
 a terminal-side attachment surface to be brought into contact with the inverter cover; and   a socket-side attachment portion attached with a socket into which a plug of the connector is to be plugged, the terminal-side attachment surface and the socket-side attachment portion being integrally molded using a die from a synthetic resin.   
     
     
         4 . The inverter according to  claim 1 , wherein:
 the first positioning unit comprises:   a first positioning hole provided to one of the inverter cover and the terminal; and   a first positioning projection provided to the other one of the inverter cover and the terminal, the first positioning projection being configured to be fitted into the first positioning hole, and   the second positioning unit comprises:   a second positioning hole provided to one of the inverter cover and the terminal case; and   a second positioning projection provided to the other one of the inverter cover and the terminal case, the second positioning projection being configured to be fitted into the second positioning hole.
